Microbial Community Resiliency and Role in Sea Level Rise

Date Issued:
2017
Summary:
The interphase (littoral zone) of the Florida Everglades and surrounding marine environments are dominated by mangrove forests and mudflats that transition into freshwater communities. As salinity levels change, plant cover of the freshwater community will be adversely affected, but perhaps more importantly, their microbial symbionts responsible for their tolerance to high salinity will be impacted as well. Microbes respond quicker to changing environments and could provide an early warning of the loss of resiliency of the Florida coastline ecosystem. For 10 weeks, soil samples from Biscayne National Park will be placed in standardized mesocosms and subject to local conditions like sunlight, tides, plants, increased sea levels, higher salinities, and variant inundation. Standard and variant conditions will be employed on different mesocosms, and weekly DNA extractions of the various soil samples will be analyzed via metagenomic analysis, creating a library of the 16S rRNA community structure over the 10 week period.
